Odessa Subarea Special Study

The Odessa Subarea Special Study is investigating the continued phased development of the Columbia Basin Project to deliver surface water from the CBP to lands currently using groundwater in the Odessa Subarea. The aquifer in the Odessa Subarea is declining to such an extent, the ability of farmers to irrigate their crops is at risk. Domestic, commercial, municipal and industrial uses, and water quality are also affected. In response to the declining aquifer and associated socioeconomic effects, Congress authorized funding for Bureau of Reclamation to investigate the problem. The State of Washington, represented by the Washington Department of Ecology, and Reclamation are co-leads and cost-share partners for the study.

The final environmental impact statement was issued on Aug. 31, 2012, in compliance with the National Environmental Policy Act and State Environmental Policy Act requirements. The record of decision was signed on April 2, 2013, and the amended ROD was signed on Sept. 27, 2013.
